   I noticed couple discrepancies in the documentation and comments of utxo_to_sqlite tool while using it, this PR fixes them. More details in the commit messages.
2. contrib: update `dumptxoutset` command in utxo_to_sqlite doc

   Running the `dumptxoutset` command without a `type` parameter leads
   to the following error. Update the tool documentation to make it
   easier to follow.
   
   `Invalid snapshot type "" specified. Please specify "rollback" or "latest"`

3. contrib: fix read metadata related comment

   The utxo snapshot metadata doesn't seem to contain any block height as per the
   CPP code and no such value is read few lines down by the tool code as well.
   
   Related CPP code: bitcoin/bitcoin/blob/28.x/src/node/utxo_snapshot.h#L60-L66

   Thanks for fixing the outdated comments! nit for the future: to refer code lines in the repo (second commit message body), it’s better to use permalinks, as otherwise these links get stale quickly
